'Nao Me Calo' App Is "Yelp For Women's Safety," Plus Four More Apps From The International Girls Hackathon That Create Safe Spaces For Women

On Tuesday, the Global Fund for Women announced "Não Me Calo" ("I Will Not Shut Up"), an app created by Brazilian girls to rank establishments based on how safe they are for women, as the winner of their International Girls Hackathon. The Hackathon brought together girls from all over the world to build apps that create safe spaces, both physical and virtual, for women.

Many of us have come back from a night out wishing we knew in advance that the dance floor was a free-for-all groping fest or the singer or comedian would individually target women with inappropriate sexual remarks. Não Me Calo can both benefit individual women by helping them avoid these situations and serve to boycott establishments that don't deserve money from patrons who don't feel safe there.

Here are some other applications to be on the lookout for if you'd like a way to avoid street harassment or even kidnapping:

1. Girls' Secret Talk, a website with a "pervert map" and "pervert radar"

A team in Taiwan created a way to track incidences of street harassment with an anonymous comments system to divulge details about the incidents. Users can receive updates about harassment taking place in their geographical locations.

2. Ohana, a sensor that tracks the locations of kidnapping victims

Coders in Oakland created a sensor small enough to attach to jewelry or a zipper so that users can activate "red mode" by holding down the sensor for five seconds to notify emergency contacts if they find themselves in an unsafe situation. Their website references the movie Lilo and Stitch:

4. Venus, a website for Indian girls to ask questions about sex

To counteract the lack of sex education in Indian schools, a group of coders from India created Venus as a safe forum for girls to ask counselors their sex questions and find reproductive health clinics. So, in case anyone was wondering whether women were good coders, they are not only creating impressive projects at young ages but also addressing issues that many men may have overlooked. And for your own entertainment and inspiration, here's a music video by singer/songwriter Carolyn Malachi announcing the winners.
